2 Safety instructions

2.1 General notes

NOTICE

Warning of damage to property and/or the environment.

The product was in perfect condition with regard to safety features when it left the

factory.

To maintain this condition and to ensure safe operation, the user must follow the

instructions and observe the warnings in this manual.

2.2 Intended use

The load cells are designed for use in table scales, counting scales, and checkweighers.

The load cells PR 40/.., PR 43/.., PR 47/.. may only be used as intended for weighing

tasks.

The dimensions of all mounting and structural components must be calculated so that

sufficient overload capacity is ensured for all loads which may occur while taking the

relevant standards into account. In particular, upright weighing objects must be

safeguarded against the weighing installation turning over or being shifted, thus

eliminating danger to people, animals, or goods even in the case of a break in a load cell

or mounting element.

Installation and repair work must only be carried out by expert/qualified personnel.

The load cells reflect the state of the art. The manufacturer does not accept any liability

for damage caused by third-party system components or due to incorrect use of the

product.

2.3 Initial inspection

Check the contents of the consignment for completeness. Check the contents visually to

determine whether any damage has occurred during transport. If there are grounds for

rejection of the goods, a claim must be filed with the carrier immediately. The

Minebea Intec sales or service organization must also be notified.

2.4 Before operational startup

NOTICE

Perform visual inspection.

Before operational startup as well as after storage or transport, inspect the load cell

visually for signs of mechanical damage.

The load cell should not be commissioned if it displays signs of visible damage and/

or is defective.

4 Installation

4.1 Safety instructions

NOTICE

Welding or lightning strike current flowing through the cell can damage it.

All electrical welding on the weighing system must be finished before mounting the load

cells.

During any additional electrical welding work near the load cell:

-Disconnect the load cell cables.

-Bypass the load cell.

-Make sure that the grounding clamp of the welding set is fitted as closely as possible

to the welding joint.

The following must be observed during installation:

-Do not lift or transport the load cell by pulling on the cable.

-Avoid shock stress (falling down, hard shocks).

-Load forces must act in the direction indicated (arrow on the load cell).

NOTICE

Changes of temperature >15 K/h may influence the measuring accuracy.

Make sure to protect the load cells from direct heating or cooling effects (sun, wind,

heat radiation, fan heaters), e.g., heat protection screens or heat protection

housings are to be installed if necessary.

NOTICE

Force shunts may cause measuring errors.

All incoming and outgoing lines (hoses, pipes, cables) must be coupled to the

measured object as flexibly as possible.

Minebea Intec EN-13

5 Connection

5.1 General information

-Protect the cable ends against contamination. Moisture must not get into the open

end of the cable.

-Keep the load cell cables away from power cables.

-The distance between measurement cables and power cables and/or components

under high voltage should be at least 1 m (reference value).

-We recommend laying the load cell cables in separate cable trays or armored steel

pipes.

-Power cables should be crossed at right angles while taking into account the

minimum distance of 1 m (reference value).

Note:

If hum interference occurs, the cable screens should only be connected on one side.

Depending on the design of the cable junction box used, either the jumper J3 must be

removed or the cable screens must be disconnected from the terminal contacts

highlighted in yellow.

WARNING

When installing in potentially explosive atmospheres:

It is imperative that you follow the application-dependent installation instructions!

Always check whether it is permissible to bilaterally connect the screens to the

equipotential bonding.

5.3 Load cell cable

The load cell cables are inseparably connected to the load cells in the factory.

The special sheathing material and the integrated strain relief with Kevlar thread ensure

extremely long service life even under difficult operating conditions.

However, despite the robust nature of the materials used, the cable should be protected

from excessive chemical and mechanical stresses. Preventing water from penetrating the

end of the cable is also important "life insurance" for the system.

6 Maintenance/repairs/cleaning

6.1 Maintenance

The load cells PR 40/.., PR 43/.., PR 47/.. are maintenance-free.

6.2 Repairs

The load cells PR 40/.., PR 43/.., PR 47/.. are designed to be robust as possible for the

required measuring accuracy and are highly reliable.

Should an electrical or mechanical defect nevertheless occur, the load cell must be

replaced.

Load cell repair is not possible.

6.3 Cleaning

Dirt on the load cell and movable parts of the scale must be cleaned as quickly as possible

-if it influences weighing, or

-if it is corrosive to the cell or cable material.

NOTICE

Some cleaning agents may not be compatible with the load cell material.

When using cleaning agents, ensure that their compatibility with the load cell

material has been tested and approved (see Chapter 3.2).

Clean the load cell with a damp cloth to avoid electrostatic charging.

and dispose of it separately from other unsorted municipal waste so that it can then be

recycled.

Before disposing of or scrapping the product, any batteries should be removed and taken

to a suitable collection point.

Please see our T&Cs for further information.

Service addresses for repairs are listed in the product information supplied with the

product and on our website (www.minebea-intec.com).
